And it was no different on Saturday when Elizabeth Olsen attended the InStyle Celebration at the Toronto Film Festival at the Windsor Arms Hotel, accompanied by her on-screen husband - and real-life rumoured beau - Tom Hiddleston.

The 26-year-old arrived in an asymmetric, high-neck, sleeveless white top and a simple pair of black trousers.

She added a touch of dazzle to the under-stated look with a pair of shiny copper heels, and a bold strike of colour with bright red lipstick.

Finishing off the stunning look, she wore her blonde tresses effortlessly around her shoulders.

Elizabeth arrived in a dramatic black gown that had a peplum top and sleeves.

Adding to the gown's glam factor were a pair of sparkling Chopard diamond rings, which were worn on her right hand.

Slip into a flounce peplum top like Elizabeth

Elizabeth Olsen turned out at the Toronto International Film Festival in one of Fashion Finder's favorite designers. She chose a runway look from Juan Carlos Obando, once a graphic designer and a young up-and-comer out of Los Angeles who's made it to the top of the fashion food chain.

We love Obando's graceful eye. Elizabeth's two-piece crepe satin sets features a black scoop-neck, long-sleeve peplum top with extra-long flounce sleeves. The skirt is sewn in a wrap configuration with a slit up to there. Simply beautiful.

We love the elegance of this look and have confidence in the future of the mighty peplum top that's been front and center in many collections for years now.

If you must have Elizabeth's top, we found it at Barneys New YOrk for $1795. If you want to shop around, please do. We discovered a find by Maje at The Outnet and a showstopper by Donna Karan at Neiman Marcus. For a simple version, look no further than H&M.
